Amazon flew a Prime Air cargo plane into Puerto Rico earlier today loaded with donations of supplies for the hurricane-ravaged U.S. territory, according to posts on social media this evening from founder and CEO Jeff Bezos.

“Amazon plane packed with donation of critical supplies landed earlier today in San Juan. Thank you to all the Amazonians who made it happen,” Bezos wrote in posts on Twitter and Instagram tonight.

Update, Oct. 3: Donated items included baby formula, bug spray, towels, tarps, tents and blankets. Amazon coordinated with officials there to ensure that the items met the needs of people in the territory.
